You are overfeeding your plant so she show a micronutrient deficiency , but is due at a nutrient lockout, flush your soil and use half nutrient dose

Help. White widow Auto day 7
I am curious about this white widow auto seedling. This is day 7. Seems to be losing a little color, but is still growing faster than the other 2 seedlings I dropped. Any suggestions on this? I have only been watering with distilled water. I have not fed any nutrients yet

Nutes over/under?
What deficiency / overfeeding? Thought it was just appearance new growth but it’s been getting worse. Newer growth is yellowish green from the centre of the leaves out (but the ridge lines of the leaf are still green) Leaves are clawed and folded less flat than lower leaves

What do you guys think? Runoff PH steady at 6.8 every time. Yellowing and red/purp stems caused by lack of cal/mag availability due to PH?

Late Stage Nutrient Issues?
As the plants near the end (last two weeks) should I expect to lose virtually all the larger/medium fan leaves as the plants drain them of nutrients or is that a sign of overall nutrient deficiency?

Magnesium deficiency? How to cure it?
Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance

need exact details on making DIY egg shell fert, (how many eggs per how much water, dilute ratios, effective dose etc, using minimal eggs and vinegar.)
How many egg shells do I need to make an effective CAL fert? Are 6 shells soaked in 500ml of water with 1tsp of vinegar enough? What about if I boiled them in plain water? What is the dosage, ratio, and minimum amount of vinegar to use for this process, so it doesn't smell

Nitrogen deficiency, light burn? Calcium?? Which deficiency?
Growing organically with happy frog mixed with a super soil concentrate. I water them with spring bottle water, ph at 7.7. Recharge every 10 days. Top dress 2-2-2 dry amendments. No clue what’s going on with this, thought it needed nitrogen. Top dress. Some new growth looks good

Should I check only EC or PH is also important?
I was told not to check for PH, add the nutes and check the EC, reach the level I want and that's it, is it right? I'm also checking the water coming out of the plants, they have EC 1+ above what I gave them. If I gave 1.5EC then it will have 2.5EC in the water coming out.
